The ZWO F80RE 0.76x reducer has been developed as a dedicated accessory for the latest ZWO FF80 APO 80 mm astrograph. It guarantees excellent field correction, thanks to which it works perfectly with professional cameras and camcorders equipped with a full-frame matrix.

This reducer reduces the focal length by a factor of 0.76x, which in the case of the ZWO FF80 APO 80 mm astrograph gives a value of 456 mm at f/5.7. Such parameters allow not only to take breathtaking photos in a wide field of view, but above all significantly shorten the exposure time.

This device allows the installation of filters with a diameter of 2", screwed into the M48x0.75 thread on the camera side. The reducer allows you to connect cameras equipped with M68x1, M54x0.75 and M48x0 threads, 75.
